COMBINTION GASOLINE SAFETY LOCK.

Application filed March 16, 1922. Serial No. 544,324.

To all uf/1,0m, it may conce/m Be it known that we, Renner C. PoR'rnoUs and JAMES A. TANNAHILL, citizens ot the Dominion of Canada, and residents of Montreal, in the county of Hochelaga and Province of Quebec, have invented certain new and useful Improvements in Combination Gasoline Safety Locks, ot which the i`o1- lowing is a specification.

The present invention comprehends the provision of a new and useful combination lock adapted to be positioned on the gas communicating means intermediate the vacuum tank and carburetter of conventional types of motor vehicles, thus providing a means whereby the gasoline supply to the engine may be shut oii' and locked, thus making it impossible for unauthorized movement ot the motor vehicle. In the method of locking automobiles now in vogue, locks used are operated by a key, with the result that the key often becomes lost and there is a possibility of the lock being picked by thieves.

In consideration of this inadequacy, we provide a lock of the character described, in which the number of partsfare few, the construction simple and the cost ot production low.

In the drawings:

Figure 1 is a vertical medial longitudinal section illustrating one form of lock.

Figure 2 is a similar view illustrating a modified form of lock.

Figure 3 is an elevation illustrating the graduation on the istulas forming a portion of the lock and Figure 4 is a section taken on line 1 -4 of Figure 2.

Referring to the various drawings in detail, similar symbols of reference designate corresponding parts.

The device will be installed either in the instrument board of the motor vehicle or in a secluded location where it can be readily operated from the drivers seat. In the acn companying drawings, the numeral 5 indicates the instrument board provided with an aperture through which the housing 6- passes, which housing is provided with a flange 7. A plurality of screws 8 pass through the said iange and seat in the inI strument board 5, thus securing the housing `to the same. Botatably positioned in the housing 6 is the fistula 9, which is provided with an enlarged terminal, the outer circum- :terential periphery of which is knurled as at 10. Thefnumeral 11 indicates an annular ring which is seated in a recess in the enlarged terminal of the fistula 9 and this annular ring is held in position by a plurality Seated in the said enlarged terminal is the annular ring 17 which is held in position by means of a plurality of setscrews 18, one of which is shown. This annular ring 17 is also provided with a bevelled face 19 which coincides with the bevelled face 2O `formed '75 on the fistula 9. The numeral 21 indicates a spindlerotatably positioned in the fistula 15. This spindle 21 is provided with an enlarged terminal, the outer circumferential periphery of which is knurled as at 22.

Seated in this enlarged terminal is the annular ring 23 which is held in position by means of a plurality of set screws 24C, one of which is shown. This annular ring- 23 is also provided with a bevelled face 50" which 85 coincides with the bevelled face 51 formed on the iistula 15. The numeral 26 indicates a casing covering the inner extremities of the locking elements. The numeral 27 indicates a washer which is positioned intermediate the inner terminals of the housing 6 andthe casing 26. A. shank 25 is formed on the opposite terminal of this spindle, which shank passes through the housing 6.

The numeral 28 indicates a similar washer 95 which is positioned on the exterior of the casing 26, which washer fits over the shank 25 of the spindle 21. The numeral 29 indicates a nut which is positioned on the shank 25 and thisnut 29 is locked in position by 100 means of a secondary nut 30. yNipplesl and 32 extend oppositely Jfrom the housing 6 and have connected on their outer terminals the conducting tubes 33 and 34, which pass through the housing 26 as illustrated.

Referring now particularly to Figure 3, for the purpose of illustration, each bevelled surface A14., 20 and 35 is divided octahedrally and each division being subdivided. The octahedral divisions will be hereinafter termed the primary divisions and the subdivisions the secondary divisions. Each primar division is designated by a letter of the alp abet, the letters being in sequence to facilitate reading of the combination. Each bevelled face of the annular rings 13, 17 and 23 is rovided with an indicating arrow.

Re erring again to Figure 1, the nipples 31 and 32 are provided with oppositel positioned apertures 36 and 37 and the stula 9 is provided with oppositely positioned apertures 3B and 41. The fistula 15 is provided with oppositely positioned apertures 39 and 40 and the spindle 21 is provided with an aperture 42. It will he readilyT understood that when these apertures are in alignment as illustrated, the same provide a free passage to allow7 the gasoline to `pass from the vacuum tank to the carburetter. When it is desired to lock the supply of gas, the fistulas and the spindle are turned so that the apertures herenbefore described are not in ali nment. It will be readily perceived that t is will not ermit the feed of gasoline. It wiil be un erstood, however, that these fistula-s and spindles will have a sufficiently .tight connection to prevent the gas from passin around the'same.

The graduate dial on the housing 6 and the stulas provide means whereby the driver of the motor vehicle can readily ascertainwhen the apertures are in registered alignment. The annular rings 13, 17 and 23 are provided with set screws as hereinbefore described and it will be understood that these rings may be shifted or turned to form various combinations as desired.

The vibration of vthe motor vehicle on which this locking device is positioned will have a tendency to shiift the fistulas and the spindle so that the apertures -will not be in vertical alignment to allow the feeding of the fuel. To overcome this inadequacy, we

provide locking means which we will now describe. Formed in the housing 6, ythe fistulas 9 ,and 15, are apertures in which .are dlsposed coil springs designated by the numerals-43. At the outer terminal =of each ucoil spring is disposed a ball indicated by .the numeral 44, which ball is held in position the upset periphery of the said apertune. In the abutting walls ofthe tstulas 9 and 15 and the spindle 21 are formed a plurality .crt concave seats 45 vdisposed in a. concentric manner as clearly illustrated in ;Fx gure.4. In operation, the balls 44 engage with these apertures and prevent accidental turning of the elements as hereinbefore set forth.

In Figure 2, we have illustrated a modified form or" lock when the spindle is divided into two sections indicated by the nuf ji merals 46 and 47 respectively. The inner terminal of section 47 is provided with a transverse ridge which seats in a groove formed in the member 46. The spindle being constructed in this manner provides a means whereby the member 47 of the spindle may be withdrawn from the lock so that the lock cannot be actuated. To secure this member 47 in position, we provide coil springs 48 having balls disposed on the outer terminals thereof indicated by the numeral 49. These balls engage with concave seats formed in the inner cylindrical surface ot the fistulas 15. The construction of this lock is otherwise congruent to the one hereinbefore described.

From the foregoing description, it is thought that the construction and o eration ot' our invention will be readily understood and while we have illustrated and .described the preferred construction of the same, we desire to have it understood that deviations from such detail in the adaptation of the device for commercial purposes may be resorted to as do not forni a departure from the spirit of the invention as defined by the appended claims.

What we claim as new is:

1. l device of' the character described constituting an outer cylindrical casing, nipples formed on the said cylindrical casing, primary and secondary fistulas disposed in the said outer ,cylindrical casing, a casing over the said nipples and one extremity of the said outer cylindrical casing, a spindle formed of two sections, the outer terminal of one section being provided with a shank. the said shank extending through the said outer cylindrical casing and locked means tor retaining the said primary fistula, secondary fistula and said shank in position,

means for connecting the sections of the spindle so that the same will turn simultaneously, aligned apertures formed in the said spindle, istulas and nipples, means for ascertaining when the said apertures are in communicating alignment and means for preventing accidental displacement ot the said free portion of spindle.

2. A device of the 'character described constituting an outer cylindrical casing, nipples carried by the said cylindrical cas'- ing, primary and secondary fistulas disposed in the said outer cylindrical casing, a casing over the said nipples and one extremity of the said outer cylindrical casing, a solid spindle, the outer terminal of said solid spindle ybeing yprovided with a shank, the said shank extending through .the said outer `cylindrical casing, locked means for retain ing fne seid primary fistula., secondary fistula zznr said spindle in position, aligned apertures :formeel n the said solid spindle, stulef; und nipples, means for ascertaining when the seid apertures are in communicating; alignment, and means for preventing aecdenta displacement of the said solid. spindle.

In testimony whereof, We aPX our signatures in the presence of two Wltnesses.
